Description

Technical Field

[0001] This invention relates to the field of welding auxiliary equipment, specifically an adjustable anti-spatter welding protection device. Background Technology

[0002] During welding operations, high-temperature weld spatter and intense light radiation are the main safety risks. The ultraviolet and infrared rays in the arc light can easily damage the operator's eyes, and the 800-degree Celsius weld spatter can also cause skin burns. Existing welding protection methods mainly include head-mounted welding masks, handheld welding masks, and a small number of external protective devices for welding torches.

[0003] However, the above-mentioned protection methods still have the following limitations in practical use: (1) Wearing a head-mounted welding mask is inconvenient and restricts the operator's head movement in confined spaces or when welding in multiple postures, and the flexibility of field of vision adjustment is insufficient. (2) Handheld welding masks require one hand, which makes welding operations inconvenient and makes it difficult to coordinate protection and operation; (3) Existing welding torch external protection devices mostly adopt rigid connection structure, and the protection angle and position cannot be flexibly adjusted, resulting in poor adaptability; (4) Traditional protective masks have limited protection range and are not effective in protecting areas such as the neck and shoulders; (5) The lack of synchronization between the protective device and the welding operation can easily lead to protection delay or blind spots.

[0004] Therefore, it is necessary to develop a welding protection device that is structurally sound, flexible in adjustment, has a wide protection range, and can be used in conjunction with welding torches. Summary of the Invention

[0005] The present invention aims to overcome the defects of the prior art and provide an adjustable anti-spatter welding protection device to solve the above-mentioned technical problems.

[0006] The technical solution adopted by the present invention to solve its technical problem is: an adjustable anti-spatter welding protection device, including a square protective glass and a welding torch connection module, wherein one side of the square protective glass is clamped and set at the front end of the welding torch connection module by a glass clamp. The welding torch connection module includes an adjustable angle component and a welding torch fixing claw. One end of the adjustable angle component is fixedly connected to the glass clamp through a connecting member, and the other end is connected to the welding torch fixing claw through a fastener to form a rotatable connection. The welding torch fixing claw is used to clamp and fix the welding torch. The adjustable angle assembly includes a multi-segment connecting rod that is connected in series along the connection direction via damping shafts. The rotation axis directions of adjacent damping shafts are different, and the damping shafts have a self-locking function, which is used to adjust the position and angle of the square protective glass in three-dimensional space and keep it stable after adjustment.

[0007] Preferably, the contact surface between the glass clamp and the square protective glass is provided with a rubber pad; the contact surface between the welding torch fixing claw and the welding torch is provided with an elastic rubber washer, and the two claws of the welding torch fixing claw are clamped and fixed to the welding torch by M6 internal hex bolts and nuts at their ends.

[0008] Preferably, the square protective glass is rectangular in shape; the connecting components are multiple hexagonal studs, and the fasteners are multiple screws.

[0009] Preferably, the square protective glass is made of borosilicate glass with a temperature resistance of ≥1000℃.

[0010] Preferably, at least one surface of the square protective glass is provided with a multi-layer light-filtering coating.

[0011] Preferably, the filter coating includes an ultraviolet light absorption layer, an infrared light reflection layer, and a visible light attenuation layer.

[0012] Preferably, the outer surface of the multilayer filter coating is further provided with an anti-fouling coating.

[0013] Preferably, the square protective glass has a side length of 180mm-320mm and a thickness of 3mm-6mm; the edges of the square protective glass are chamfered.

[0014] Preferably, the adjustable angle assembly includes a multi-segment connecting rod that is sequentially connected in series along the connection direction via a damping shaft; the self-locking torque of the damping shaft is ≥5 N·m.

[0015] Preferably, the welding torch connection module is I-shaped, and the adjustable angle component is made of 304 stainless steel.

[0016] The beneficial effects of this invention are: (1) The present invention directly installs the square protective glass onto the welding torch through the welding torch connection module, so that the protective device moves synchronously with the welding torch. During the welding process, the operator does not need to adjust the position of the protective device separately, which avoids the restriction of head movement by the head-mounted welding mask and the problem of the hand-held welding mask occupying the operator's hand, and significantly improves the flexibility and operational coordination of welding operations. (2) The present invention adopts an adjustable angle assembly consisting of a multi-segment connecting rod and multiple damping shafts connected in series. The rotation axis directions of adjacent damping shafts are different, so that the square protective glass can be adjusted in position and angle in three-dimensional space. It can flexibly adapt to various welding postures such as flat welding, vertical welding, horizontal welding and overhead welding, and overcomes the problems of fixed protection angle and poor adaptability of existing welding torch external protective devices. (3) The damping shaft of the present invention has a self-locking function. After the position and angle of the protective glass are adjusted, it can maintain a stable state during the welding operation, effectively preventing the protective glass from shifting due to the movement of the welding torch, vibration or slight collision, thus improving the safety and reliability of the welding protection process. (4) The present invention adopts a square protective glass structure, which has a larger protective area than traditional welding masks or partial protective sheets. It can effectively block welding arc light and high-temperature welding slag splashes, not only protecting the operator's eyes, but also providing more comprehensive protection for the face, neck and shoulders, reducing the risk of burns. (5) The square protective glass of the present invention has at least one surface with a multi-layer filter coating, which can effectively filter ultraviolet and infrared rays generated during the welding process and attenuate visible light, thus ensuring the visibility of the welding operation while effectively reducing the damage of arc radiation to the operator's eyes. (6) The square protective glass of the present invention is made of high temperature resistant borosilicate glass with chamfered edges, which can withstand the high temperature spatter generated during welding and avoid the safety hazards caused by sharp edges; at the same time, the rubber pad and elastic rubber gasket ensure reliable connection and avoid damage to the glass and welding torch during clamping, thus improving the overall durability of the device. (7) The present invention has a compact overall structure. The welding torch connection module adopts an "I" type structure and is made of metal material. It has high strength and small size, and is suitable for use in narrow spaces such as pressure vessels and pipelines. It solves the problem of the inconvenience of using traditional welding masks in confined spaces. (8) This invention combines the three-dimensional adjustment capability of the multi-segment damping shaft with the single-sided clamping structure of the square protective glass, so that the protective glass can be flexibly adjusted according to the changes in the welding torch posture while maintaining a large protective area. This enables stable and continuous protection in narrow spaces and multi-posture welding conditions, avoiding the blind spots caused by the fixed structure of existing protective devices.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1

[0022] like Figures 1-2 As shown, the present invention provides an adjustable anti-spatter welding protection device, comprising a square protective glass 1 and a welding torch connecting module 2, wherein one side of the square protective glass 1 is clamped to the front end of the welding torch connecting module 2 by a glass clamp 3. In practical use, since the square protective glass is installed by clamping on one side, its other edge areas are not obstructed by the structure, so the protective glass has a larger effective protection area in the same installation space; combined with the multi-directional adjustment capability of the adjustable angle component, the present invention achieves a balance between protection range and adjustment flexibility without increasing the size of the device.

[0023] like Figures 3-6 The welding torch connection module 2 shown includes an adjustable angle component 21 and a welding torch fixing claw 22. One end of the adjustable angle component 21 is fixedly connected to the glass clamp 3 through a connecting member, and the other end is connected to the welding torch fixing claw 22 through a fastener to form a rotatable connection; it is used to adjust the position and angle of the square protective glass 1 relative to the welding torch 4; the welding torch fixing claw 22 is used to clamp and fix the welding torch 4 to achieve a reliable connection between the protective device and the welding torch; The adjustable angle assembly 21 includes a multi-segment connecting rod 211 that is connected in series along the connection direction via damping shafts 5. The rotation axis directions of adjacent damping shafts 5 are different, which allows the square protective glass 1 to be adjusted in position and angle in three-dimensional space. The damping shafts 5 have a self-locking function, which can keep the position of the protective glass stable after the adjustment is completed, and prevent it from shifting due to the movement of the welding torch, vibration or slight collision during the welding operation.

[0024] An adjustable angle assembly formed by multiple damping shafts connected in series enables the square protective glass to dynamically adjust with the welding torch posture, thereby maintaining an effective protective position under different welding postures and avoiding the problem of the protected area deviating from the welding arc light due to changes in the welding torch angle.

[0025] Preferably, a rubber pad is bonded to the contact surface between the glass clamp 3 and the square protective glass 1 to increase the clamping friction and prevent damage to the square protective glass 1 during the clamping process. The contact surface between the welding torch fixing claw 22 and the welding torch 4 is provided with an elastic rubber gasket, which is used to adapt to welding torches of different diameters and prevent the surface of the welding torch from being pinched. The two claws of the welding torch fixing claw 22 are clamped and fixed to the welding torch 4 by the M6 ​​internal hex bolts and nuts at their ends.

[0026] Preferably, the square protective glass 1 is rectangular in shape and is used to block the arc radiation and high-temperature weld spatter generated during the welding process, thereby protecting the eyes, face and neck area of ​​the welding operator.

[0027] The connecting components are two hexagon socket studs, and the fasteners are two screws; one end of the adjustable angle component 21 is connected to the glass clamp 3 through two hexagon socket studs, and the other end is connected to the welding handle fixing claw 22 through two screws, thus forming a rotatable connection structure.

[0028] Preferably, the square protective glass 1 is made of borosilicate glass with a temperature resistance of ≥1000℃, which can withstand the high-temperature spatter generated during welding operations without cracking. Its edges are chamfered to avoid sharp edges causing injury to operators.

[0029] Preferably, at least one surface of the square protective glass 1 is provided with a multi-layer light-filtering coating.

[0030] Preferably, the light-filtering coating includes an ultraviolet light absorption layer, an infrared light reflection layer, and a visible light attenuation layer, which are used to reduce the damage of welding arc light to the operator's eyes.

[0031] Preferably, the outer surface of the multilayer filter coating is further provided with an anti-fouling coating to reduce welding slag adhesion and facilitate cleaning.

[0032] Preferably, the square protective glass 1 has a side length of 180mm-320mm and a thickness of 3mm-6mm; the edges of the square protective glass 1 are chamfered.

[0033] Preferably, the adjustable angle assembly 21 includes a multi-segment connecting rod 211 connected in series along the connection direction via a damping shaft 5; the self-locking torque of the damping shaft 5 is ≥5 N·m to ensure the stability of the protective glass during the welding process.

[0034] Preferably, the welding torch connection module 2 is I-shaped, and the adjustable angle component 21 is made of 304 stainless steel to improve the structural strength and durability of the device.

[0035] Example 2

[0036] like Figures 1-2 In this embodiment, based on the structure described in Embodiment 1, the working principle of the adjustable anti-spatter welding protection device used in conjunction with the welding torch during welding operations is explained as follows: Before operation, the operator uses the welding torch fixing claw 22 to fix the welding torch connecting module 2 onto the welding torch 4, so that the square protective glass 1 is connected to the welding torch 4 through the glass clamp 3 and the adjustable angle assembly 21. Subsequently, according to the welding position and welding posture, the operator adjusts the rotation angle of each damping shaft 5 in the adjustable angle assembly 21 in sequence, so that the square protective glass 1 moves and rotates in three-dimensional space to the front of the direction of the welding arc and welding slag spatter.

[0037] Since the adjustable angle assembly 21 includes a multi-segment connecting rod 211 that is connected in series along the connection direction via the damping shaft 5, and the rotation axis directions of adjacent damping shafts 5 are different, the square protective glass 1 can achieve composite adjustment in multiple directions, thereby adapting to the protection requirements under different welding conditions.

[0038] After the position and angle adjustment is completed, the self-locking function of the damping shaft 5 keeps each shaft at the current adjustment angle, so that the square protective glass 1 remains stable during the welding operation and prevents it from shifting due to the movement of the welding torch 4, vibration or slight collision.

[0039] During the welding operation, as the welding torch 4 moves, the square protective glass 1 moves synchronously under the drive of the welding torch connecting module 2, always positioned on the path of the welding arc light and high-temperature welding slag spatter, blocking and filtering ultraviolet rays, infrared rays and strong visible light generated during the welding process, while blocking high-temperature welding slag spatter, thus providing continuous and effective protection for the operator's eyes, face and neck area.

[0040] This embodiment also includes a welding clamp 6, which is used to clamp and support the welding torch 4 during the welding operation so that the welding torch 4 remains relatively stable during the welding process.

[0041] Through the above-described working method, this embodiment achieves coordinated operation between the protective device and the welding operation, enabling the protective action to be completed without additional operation, reducing the risk of protective delay or blind spots during the welding operation, and improving the safety and reliability of the welding operation.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
